In certain games if I move my mouse slowly to look around or something like that, the screen/cursor won't move at all. I have to move my mouse past a certain speed before everything on the screen starts moving. VERY annoying, basically makes the game unplayable for me. I'm using a logitech gaming mouse, tried a generic mouse as well and both behave this way. Tried installing the logitech software and updating it to the newest version. I can make it behave better my messing with pointer speed and acceleration, but the issue is still there. First noticed the problem on Vista x64 in the game Alice.. does it on "some" other games like Ghostbusters. I've since upgraded to Windows 7 and the problems is still there. Has anyone seen this behavior before and have a fix for it?
